Control shifted to fund partner Ian Hathaway. OpenAI said Altman had no personal financial interest in the fund, so the change was not evidence that he sold a stake or gave up investment profits. The distinction matters: legal authority to manage a fund is not the same as economic ownership.
What changed, and when?
The change concerned the fund’s management structure, not Altman’s position at OpenAI. Reuters reported that a filing dated March 29, 2024 documented Altman’s departure from the fund’s general-partner control role and Hathaway’s assumption of that role. OpenAI described the original arrangement as temporary and said the new structure offered greater clarity. Reuters reported the change on April 1, 2024.
That timing is important: this is a 2024 governance change, not a new development in 2026. Later SEC filings identify Hathaway in management roles for particular Startup Fund vehicles, including a filing signed August 4, 2025. Those records support saying he was the publicly named control person for those entities; they do not establish that every fund vehicle has an identical ownership structure.
What did “owning” the fund mean?
The OpenAI Startup Fund was associated with OpenAI by name and invested in AI-related startups, but its original legal structure placed Altman in a general-partner management role rather than making the fund a straightforward OpenAI-owned corporate division. The distinction between the brand, the fund’s legal manager, and its investors explains why headlines describing Altman as the owner can mislead.

- Brand affiliation: The fund used the OpenAI name and invested in startups, but that alone does not establish that OpenAI owned the fund.
- General partner: The general partner, or its manager, has authority over fund operations and investment decisions under the fund’s structure. SEC filings named Altman in this management capacity for the original fund.
- Limited partners: These are investors who contribute capital and generally do not manage the fund’s investments.
- Economic interest: This concerns whether someone is entitled to investment profits, fees, or carried interest. It is separate from managerial control.
OpenAI said Altman had no personal financial interest in the fund. That is the company’s reported position, not proof that the public filings disclose every detail of the fund’s economics. There is no evidence in the cited material that he sold an economic stake when the management structure changed. Reuters’ account includes OpenAI’s statement about Altman’s financial interest.
What the SEC filings show
The filings provide a documentary trail of named fund managers. They concern separate legal vehicles, so the entries should not be collapsed into a claim that one person owned every OpenAI-associated fund.
| Fund vehicle | Filing evidence | Named management role |
|---|---|---|
| OpenAI Startup Fund I, L.P. | 2021 Form D | Sam Altman, manager of the general partner |
| OpenAI Startup Fund I, L.P. | 2023 filing | Sam Altman, manager of the general partner |
| OpenAI Startup Fund SPV I, L.P. | 2024 Form D | Ian Hathaway, managing member of the general partner |
| OpenAI Startup Fund SPV V, L.P. | 2024 Form D | Ian Hathaway, manager of the managing member of the general partner |
| OpenAI Startup Fund SPV VI, L.P. | Form D signed August 4, 2025 | Ian Hathaway, manager of the managing member of the general partner |
Sources: 2021 Form D, 2023 filing, SPV I Form D, SPV V Form D, and SPV VI Form D.
Form D is a notice related to an exempt securities offering, not an SEC endorsement or confirmation of the investment’s merits. The filings identify people in specified management roles; they do not, by themselves, explain the complete ownership chain or the fund’s fees, carried interest, assets, or investor returns.
Why did the arrangement draw scrutiny?
Altman was OpenAI’s CEO while also being named as the manager of the general partner of a fund using OpenAI’s name. The fund raised outside capital, reportedly including money from OpenAI partners such as Microsoft; Reuters reported that OpenAI itself was not an investor. Contemporary coverage put fundraising at about $175 million, a reported amount raised—not a current valuation or a measure of investor returns. Reuters’ report describes the fundraising and investor context.
That combination prompted governance questions: who controlled investment decisions, what duties applied to the fund’s manager, and how the arrangement fit with OpenAI’s mission and corporate governance. Those are legitimate questions about transparency and potential conflicts; they are not, on their own, evidence of misconduct or a legal violation. Reuters also reported that an independent investigation following Altman’s November 2023 ouster found no wrongdoing relating to product safety or OpenAI finances. That finding should not be stretched into a ruling on every question about the Startup Fund.

Who is Ian Hathaway?
Hathaway was a partner at the fund from its early period. OpenAI said he oversaw its accelerator program. Reuters associated him with investments in Harvey, Cursor, Speak, and Ambience Healthcare. Subsequent SEC filings place him in general-partner management roles for several later fund vehicles. These records establish a leadership and control role for the named entities, not a purchase of Altman’s personal stake.
What remains unclear?
The available public filings and reporting establish a change in disclosed management, but do not fully resolve the legal relationship between OpenAI and every Startup Fund entity or the fund’s detailed economics. They also do not establish whether any restructuring took place after the August 4, 2025 SPV VI filing. The absence of a later filing in the cited record is not proof that no later change occurred.
